Cu2SO3, also known as Copper (II) Sulfite, is a chemical substance with the chemical formula Cu2SO3. In Vietnamese, it is referred to as sulfua đồng (II).
It consists of two copper (Cu) atoms, one sulfur (S) atom, and three oxygen (O) atoms. The atomic mass of Cu2SO3 is 223.15 g/mol. Its ionic structure includes two copper ions Cu2+ and one sulfite ion SO3^2-.
In terms of physical properties, Cu2SO3 usually appears as a blue or white powder with no specific smell and an undefined pH level. In high school level knowledge, information on the chemical properties of Cu2SO3 is not widely discussed.
There are several commonly encountered chemical reactions with Cu2SO3, such as reaction with strong acid to produce SO2, CuSO4, and H2O, or reaction with alkali metals to produce Cu and other types of sulfite salts.
The synthesis of Cu2SO3 can be performed in a laboratory through the reaction between CuSO4 solution and Na2SO3 solution. In the industry, Cu2SO3 can be produced from the reaction between copper and sulfur, followed by a reaction with oxygen.
